摘要
建造一座木材工业生产厂是需要达到一系列的国家立法要求。而达到这些要求是通过严格的科学研究和调查而得来的。在一个项目中,通常这是一个关键环节。大多高度工业化国家都具有严格的法律条例控制放射性粉尘和气体对环境所造成的污染。本文讨论的是在木材工业干燥过程的内部,什么是造成环境污染的环节因素,以化工生产条件所带来的影响为例,输入原材料的选择,干燥炉的设计,运作程序,以及燃料的选择。上述因素将会对烟囱污染带来什么样的影 响?本文采用国际通用的分析手法,准确地分析了放射性粉尘积累以及如何控制由此造成的空气污染。根据研究调查的积累进一步探讨如何以最佳的设计系统而达到控制污染。以冷凝缩代替热干燥将是一个新的值得考虑的工业化革新。参14。
The requirements that a business needs to consider when building a wood panels manufacturing plant are much the same as they have been for decades, but today there is also the need for multiple environmental studies and permits. These are costly and time consuming additional expenses that often are the longest lead-time items on any project. Most industrialized countries have legislation in place to limit and control the negative impact that emission of pollutants may have on the environment. This paper discusses what is actually happening inside wood drying plants, and the prerequisite conditions for genesis of pyrolytic products relative to the operational parameters, such as choice of input raw materials, driers design and operational regime, choice of fuels for the heat generation and how these factors influence production of stack emission. The characterization of emission condensate by analytical methods is described, and survey of emission control system in use worldwide is described, and means of investigating what may be the optimum design for the control of emission is discussed. Alternate uses of utilizing the condensate, other than burning, are presented for consideration.
